In order to test the efficiency of the finder/fitter, we must first determine whether a track is "reconstructible" or not. (See COMPASS-Note 2004-1 section 5.1 and Mankel Rep. Prog. Phys. 67 (2004) 553-622 section 2.5.1)

We do this here by checking if the "death" point of the track is inside or outside of some inner volume of the detector. Specifically, if the death point is outside of a cylinder of radius 45cm and z-extent covering from the upstream end of the CDC to the downstream end of the 2nd FDC package. This ensures that it either passes through the first 2 layers of the outermost axial superlayer of the CDC or, the first 2 packages of the FDC.

Note that the beam hole is not considered here. It is assumed that efficiency plots will be made either with a cut on theta or plotted against theta in order to accomodate that area.
